DataPortals.org is the most comprehensive list of open data portals in the world. It is curated by a group of leading open data experts from around the world – including representatives from local, regional and national governments, international organisations such as the World Bank, and numerous NGOs.

The alpha version of DataPortals.org was launched at OKCon 2011 in Berlin. We have plenty of useful improvements and features in the pipeline, which will be launched over the coming months.

If you have an idea for a feature you think we should add, please let us know via the discussion forum.

The Open Definition

The Open Definition sets out principles that define “openness” in relation to data and content.

It makes precise the meaning of “open” in the terms “open data” and “open content” and thereby ensures quality and encourages compatibility between different pools of open material.

It can be summed up in the statement that:

“Open means anyone can freely access, use, modify, and share for any purpose(subject, at most, to requirements that preserve provenance and openness).”

Put most succinctly:

“Open data and content can be freely used, modified, and shared by anyone forany purpose”
